This works well and preserves the vector +nature of the original \s-1EPS\s0. Unfortunately, \fBdvips\fR does not read +\&\s-1PDF\s0, so two versions of the graphic must be maintained if the document +is to be processed with both \fBlatex\fR+\fBdvips\fR and \fBpdflatex\fR. +.IP "\s-1PNG\s0" 4 +.IX Item "PNG" +\&\s-1PNG\s0 is a bitmap format and therefore scales poorly. Also, \fBdvips\fR +does not read \s-1PNG\s0, so two versions of the graphic must be maintained +if the document is to be processed with both \fBlatex\fR+\fBdvips\fR and +\&\fBpdflatex\fR. +.IP "\s-1JPEG\s0" 4 +.IX Item "JPEG" +\&\s-1JPEG\s0 is a bitmap format and therefore scales poorly. Also, \fBdvips\fR +does not read \s-1JPEG\s0, so two versions of the graphic must be maintained +if the document is to be processed with both \fBlatex\fR+\fBdvips\fR and +\&\fBpdflatex\fR. +.IP "\s-1MPS\s0" 4 +.IX Item "MPS" +This is probably the least-used \fBpdflatex\fR\-compatible graphics +format. \s-1MPS\s0 is actually a stylized version of \s-1EPS\s0 that MetaPost +outputs. Like \s-1PDF\s0, \s-1MPS\s0 is a vector format and remains as such when +imported into a \fBpdflatex\fR document. Also like \s-1PDF\s0, \fBdvips\fR does +not read \s-1MPS\s0, so two versions of the graphic must be maintained if the +document is to be processed with both \fBlatex\fR+\fBdvips\fR and +\&\fBpdflatex\fR. +.PP +The insight behind \fBpurifyeps\fR is that there are only a few, small +differences between \s-1MPS\s0 and \s-1EPS\s0 and that a file can be converted into +a format that matches both the \s-1MPS\s0 and \s-1EPS\s0 specifications +simultaneously. \fBpurifyeps\fR inputs an \s-1EPS\s0 file, uses \fBpstoedit\fR's +\&\f(CW\*(C`mpost\*(C'\fR filter to convert the file to MetaPost (\fI.mp\fR), runs +\&\fBmpost\fR on the file to convert it to \s-1MPS\s0, and finally performs some +touchups on the result to convert the file back to \s-1EPS\s0, while +preserving its ability to be parsed by \fBpdflatex\fR. +.SH "OPTIONS" +.IX Header "OPTIONS" +.IP "\fB\-\-help\fR" 4 +.IX Item "--help" +Display \*(L"Usage\*(R" and \*(L"Options\*(R" from the \fBpurifyeps\fR documentation. +.IP "\fB\-V\fR, \fB\-\-version\fR" 4 +.IX Item "-V, --version" +Display the \fBpurifyeps\fR version number, copyright, and license. +.IP "\fB\-\-fontmap\fR=\fI.fmp file\fR" 4 +.IX Item "--fontmap=.fmp file" +Specify the name of a file that tells \fBpurifyeps\fR how to map from TeX +font names to PostScript font names.

The same filename can safely be used for both files. If +the output filename is omitted, output will go to the standard output +device.

Error messages +produced by \fBpstoedit\fR and \fBmpost\fR are sometimes silently ignored. +Also, errors sometimes cause \fBpurifyeps\fR to leave temporary files +(\fIpurifyeps\-\fR\fI#####\fR) lying around. +.PP +\&\fBpurifyeps\fR is subject to all of the limitations that affect +\&\fBpstoedit\fR and especially the \f(CW\*(C`mpost\*(C'\fR backend to \fBpstoedit\fR. As a +result, \fBpurifyeps\fR ignores certain PostScript constructs, such as +nonuniformly scaled text. +.SH "NOTES" +.IX Header "NOTES" +\&\fBpurifyeps\fR needs a file that tells it how to map from TeX font names +to PostScript font names. This file must contain two, space-separated +columns. The first lists a PostScript font name, and the second lists +the TeX equivalent. Blank lines and lines that start with \f(CW\*(C`%\*(C'\fR are +ignored.

By +default, \fBpurifyeps\fR looks in the current directory for a font map +called \fImpost.fmp\fR. The \f(CW\*(C`\-\-fontmap\*(C'\fR command-line option tells +\&\fBpurifyeps\fR to use a different font map, which will typically be the +\&\fImpost.fmp\fR file that comes with \fBpstoedit\fR. +.PP +Once you create purified \s-1EPS\s0 files with \fBpurifyeps\fR, you need to +instruct \fBpdflatex\fR to use them. The pdfLaTeX configuration of the +\&\f(CW\*(C`graphics\*(C'\fR and \f(CW\*(C`graphicx\*(C'\fR packages (\fIpdftex.def\fR) normally ignores +\&\fI.eps\fR files.
